>How-To-Repeat:
	Used devices are:
	* ASRock J4125-ITX mainboard;
	* 32GB of main memory was populated;
	* AHCISATA device card was populated in the M.2 Wi-Fi slot;
	* Intel i225-V rev.3 device card was populated in the PCIe slot;
	and try to boot kernel (with igc debug code enabled)
	if the i225-V was unplugged, then the kernel works normally.
>Fix:
	unknown.

>Unformatted:
 	kernel source fetched as of 2026-01-02
